Hioki compact 1 or 2-channel data loggers feature a 60,000 data set/channel memory to measure temperature, humidity, voltage or instrumentation signals. The LR5001 logs temperature and humidity over 2 channels in as fast as 1 second intervals.
| Measurement items | Temperature 1 ch and Humidity 1 ch (Requires included or optional humidity sensor) |
| Measurement range | Temperature: -40.0°C to 85.0°C, Humidity: 0 to 100% RH at sensor environment |
| Basic accuracy |
[Temperature]: ±0.5 °C (main unit + sensor accuracy, at 0.0 to 35.0 °C) [Humidity]: ±5 % RH (main unit + temperature/humidity sensor LR950x combination, at 20 to 30 °C / 10 to 50 % RH) Note: Basic accuracy is typical value, refer to the detailed catalog |
| Storage capacity | Instantaneous value mode: 60,000 data, Statistical value mode: 15,000 data |
| Recording interval | 1 to 30 sec., 1 to 60 min., 15 selections |
| Recording modes |
Instantaneous recording: at every recording interval Statistical value recording: Measure at one-second intervals, and record the instantaneous, maximum, minimum, and average values within every recording interval |
| Recording methods |
One-time recording: Stop recording when the memory capacity is full Endless recording: Continue recording even when the memory capacity is full (old data is overwritten) Start: Logger button operation or scheduled time Stop: Logger button operation or scheduled time, or auto-stop when the memory capacity is full (at one-time recording) |
| Other functions |
